331 AM EDT TUE AUG 22 2023
VALID 00Z WED AUG 23 2023 - 00Z WED AUG 30 2023
A RATHER UNEVENTFUL WEATHER PATTERN IS EXPECTED ACROSS THE HAWAII
DOMAIN FOR THE UPCOMING WEEK, WITH THE MAIN SURFACE HIGH ANCHORED
IN PLACE WELL NORTHEAST OF THE ISLANDS NEAR 40N/150W THROUGH THE
END OF THE WORK WEEK BASED ON THE LATEST MODEL GUIDANCE. THIS
HIGH MAY THEN DRIFT SOME TOWARDS THE SOUTH NEXT WEEKEND AND A COL
IN THE RIDGE AXIS MAY DEVELOP NORTH OF THE WESTERN ISLANDS AS A
FRONTAL BOUNDARY APPROACHES THE REGION FROM THE NORTHWEST, BUT NOT
EXPECTED TO HAVE ANY NOTEWORTHY IMPACTS AT THIS TIME.
IN TERMS OF SENSIBLE WEATHER, TRADE WIND FLOW SHOULD GENERALLY BE
OUT OF THE EAST AT 10-20 MPH MOST DAYS THROUGH FRIDAY, AND THEN
PERHAPS VEERING SOME TO THE ESE NEXT WEEKEND AS THE COL DEVELOPS
NORTHWEST OF THE STATE. NO MAJOR INCURSIONS OF TROPICAL MOISTURE
ARE EXPECTED AFTER THE PASSAGE OF THE REMNANTS OF FORMER T.S.
FERNANDA, WITH TYPICAL TRADE WIND ENHANCED SHOWERS ON THE WINDWARD
TERRAIN.
